Cooling depending on outdoor temperature
With setting “set. AT” set temperatures are ignored. Instead, set
temperatures are automatically calculated based on the outdoor
temperature.
The calculation is based on the value entered in Kelvin under
“Outd. T-Dif1” but is restricted to a spread of 1K– 10K (adjusta-
ble in 0.5 steps).
A Temperature
B Time
1 Outdoor temperature
2 Set temperature mixing circiut
3 set. AT (= outdoor temperature dierence)
ENABLE ACTIVE COOLING
NOTE
The active cooling function can only be used if the system
is utilised in accordance with the corresponding hydraulic
diagram.
There is otherwise no guarantee that the active cooling
with function properly.
The active cooling function may only be used if the heating and
heat pump regulators are equipped with software >4.31.
COOLING BASED ON SET TEMPERATURE OR
DEPENDING ON OUTDOOR TEMPERATURE
The cooling can be released based on the outdoor temperature
or in accordance with a xed temperature (= set temperature).
Cooling based on set temperature
With the “xed Tp” setting, the supply temperature of the cooling
represents the setpoint temperature set for the mixing circuit1
(MC1):
A Temperature
B Time
1 Outdoor temperature
2 xed Tp ( = set temperature mixing circuit)
